This invention relates to a new and improved guide plate for loose leaf binders."

In the use of loose leaf binders ofthe type usually called post binders it is frequently necessary to remove from'the binder a sheet which is located a considerable distance below the top sheet; In order to accomplish this it is necessary to remove from the posts all of the sheets which are positioned above the sheet which it is desired to remove. When this is done a considerable amount of time and manipulation is necessary toreplace on the posts the sheets which have been removed because when a considerable number of sheets are to be replaced it is diiiicult, if not impossible, to aline the holes in thesheets so that they may be allreplaced at the same time.

It is also diflicult in books of this character to replace in the proper position the upper cover which, of necessity, has been removed when it is desired to remove sheets from the book. I c f The main object of my invention is to provide a device to be used in conjunction with a loose leaf post binder which will permit the removal fromthe posts of-any desired number of sheets andthe replacement of the samein one operation;

Another ob'ectis to provide a devicewhich will also act as a guide and positioning means for the cover which has been removed when the same is replaced in position. V

' Another object is to provide a device which will'permit the use in a loose leaf binder of 5 sheets which have recesses for the reception of the posts. which recesses are thesame width as the posts so that the sheets may be placed on the posts without the necessity of 7 first distorting theme in order-to 7 permit the insertionofthe posts.

Other objects and advantages relate to the size, shape and association of parts all as will mores fully appear from the following description taken in connection with the ac?- companying drawings in which Figure 1 is a perspectiveview, partially broken away, of a'post binder in the open position and with my device in place,

One edge of bottom plate is projecting eye port-ions 9+ between which are received eye portions 10 of cover A pintle (not shown) is passed 5 d 1,0 to

through eye 1 portions 1 ]9, an hold thesaine together and to create what is in effect a piano. hinge. A cover 12 ofthe same cross section as bottom plate V- 6, is

fitted'on bottom plate 6 to form a hollow approximately rectangular casing. An end .plug '13- ispositioned inone end of the casing formed b-y' cover 42- and'bottom plate 6' 'and carries on itsinnerface a socket at 15' for a, purpose hereinafter to be described; 'Another end plug is positioned in the opposite end of the casing and is formed with acylindrical hole at I ,16 for a purposeihereinafter to be, 'de-j' scribed; A bearing plate 18- is positioned rod il9' extends the length of casing formed by cover 12 and bottom plate -6-+ adj acentto one side thereof and having one end journaled in socket 15- and the other endjournaled in bearing plate --1.8e

into the hole 16 and the part -20 of rod 19- which extends into hole -16 is square in cross section for engagement with a key or crank (not shown). One end of rod 19 carries a right hand thread -2l and the opposite end of rod 19 carries a left hand thread 22. Looking nuts 23 and 245 are carried on the threaded ends 21 and 22 respectively of rod- 19 and are of such a shape thatthehousing 1. will prevent their rotary movement when the rod 19 is rotated. A guide plate 25 is ositioned in housing 1 at; approximate y the center point thereof, and a guide rod 26 extend'sthrough guide plate 25 and bears on end plugs 13 and '14. Guide rod 26 is positioned parallel to rod 19 and adjacent the opposite side of housing -I. Flexible posts 27 and 28 are inserted into housing 1- through holes 7.

These flexible posts 27 and 28 are similar in construction and are preferably made of tongue and groove links 29- held together by pintles 30. The inner ends of flexible posts 27 and 28 carry guide links 31- and 32 respectively, said guide links being movably mounted on guide rod 26. Guide rod 26 also carries a spring retaining collar33-- abutting against end plug 13 and a slidable spring retaining collar -33" normally abutting against guide link 31. A spring 34= is interposed between the spring retaining collar 33- and the spring retaining collar 33, said spring 3t encircling guide rod 26'. Similarly a spring retaining collar 35 is carried on guide rod 26 abutting against end plug 14, and a similar spring retaining collar 36 is carried on guide rod 26 and is slidable thereon and normally abuts against guide link 32. Similarly a spring 37 encircles guide rod 26 and bears against spring retaining collars 35 and 86.

Lock nuts 23- and 24. extend downwardly through holes 77 in bottom plate .6 and have curved faces adjacent flexible posts 27 and 28 respectively. The proportions of lock nuts 23 and 24- are such that when they are moved inwardly by the rotation of rod 9 they will be forced against flexible posts 27- and 28 to 'to hold the same locked in position.

The socket 15 is of a sufficient depth with relation to the length of rod 19 that a limited longitudinal movement of rod 19 is permitted so that in all cases lock nuts 23 and 24. will simultaneously conthe outside edges of holes 'Z7 in a position to act as guides for flexible posts -27 and 2'8 when they are moved in and out -proximately rectangular casing.

through holes 77. A protecting plate 37 having spaced holes 38 and 39- for permitting the passage of flexible posts 27 and 28 is positioned on the underside of bottom plate 6 and is formed so as '7.

7 section and which carries spaced holes 43- and 44 positioned so as to register with holes 77 in housing 1. Upwardly extending curved guides 45 and 48, are positioned on the inner edges of holes 43 and 44 respectively. One edge of top plate 42 carries a plurality, in this case four, of projecting eye portions between which are received registering eye portions of cover 4 which eye portions are held together to form a hinge by a pintle. The hinge construction for housing 2- is not shown in the drawing but is similar in all respect to the hinge construction of housing l previously described. A bottom plate 4:7 similar in cross section to top plate 42- is fitted onplate 42 to form a hollow ap- An end plug 48- is positioned in the end of the casing formed by top plate 42 and bottom plate 47 and carries on its inner face a socket not shown for a purpose hereinafter described. A bearing plate 50 is positioned adjacent the inner face of end plug 48.

Another end plug 51 is posi-- tioned in the opposite end of the casing.

A hearing plate 53 is positioned adjacent the inner face of end plug 51-. A guide plate 54 is positioned in the casing formed by top plate 452 and bottom plate 47 at approximately the center point thereof. A rod 55, carrying on one end a right hand thread 56 and on the opposite end a left hand thread 57, is positioned adjacent one longitudinal side of the casing formed by top plate 42- and bottom plate 47 and has one end journaled in bearing plate 50. The other end of rod 55 is journaled in bearing plate 53 and has an extension 58, square in cross section, extending into cylindrical hole 52. The square end 58 is designed to receive a key or crank (not shown) by which rod 55- is rotated. Nuts 59 and 6'0' are threaded on threads 57 and 56 respectively. The opposite ends receiving in its other end end section 71 forthe I of flexible posts 27- and 28- heretofore describ'edare inserted through holes 4A and .45 and are connected by links j6l and 62 to nuts and V59 respectively. A, protecting plate[63 having spaced holes 64 and registering with holes 43- and 44- respectively is positioned on the upper side of top plate 42 and is of such a form and shape as to have its upper surface adjacent the upper edges of guides 45 and 4t6. Protecting plate 63-, top plate t2-, and plug 48 and bottom plate 47 are secured together by rivet '66. Similarly protecting plate 63, top plate &2, end plug 51 and bottom plate 47 aresecured' together by rivet 67. V

For use with the binder I provide a guide plate 68 in this case substantially U- shaped in cross section to conform to one face of housing -1. It will be understood that the exact shape of guide plate 68 will depend upon'the type of binder with which it is to be used, the requirement being that its shape shall conform to the shape of one facg of the housing with which it is to be use I "On the bottom of guide plate '68 I provide a plurality, in this case shown as two, of downwardly extending posts '-69 which are preferably of the extensible type havinga base portion 70- alfixed to guide plate 68 and an end portion 71- threaded into base portion 70 so that, if desired, end section 7 1 may be unscrewed from base section 70+ and a filler section, not shown, screwed into base section70 and purpose of making the posts of greater length. I also provide in guide plate 68 a pluralzity, in this case shown as two, of apertures In assembling my device I place one of the guide plates -68 onhousing 2' and place thereupon sheets '5 which are provided with apertures through whichposts -69- extend and which also are provided with apertures registeringwith holes 72 I then place a second guide plate 68. on the upper surface of the topmost sheet 5 with its posts 69 extending downwardly through the apertures in sheets 5 which are in registration withthe holes 7 2' in the guide plate 68 which is in position on housing Holes 72 in guide plates 68 are provided so that if it is desiredthe posts 69;- in one guide plate 68- will'extend-through the sheets 5 into holes 72 andvice versatogive greater rigidity to the "book when the same is in the locked position.

With the two guide plates 68 in position V as just described I place housing 1 in registration with the guide plate 68 which is book.

tion to move 'nuts 59 and 60 away fromthe center of the housing and force portions of tion'to draw nuts 59 and 60itowards the cen .ter of housing 2?-"which will result in shortening the posts between housin'gsl and '2 and will/lock the different parts of the structure together.

flexible postsf'27 and 28 out of the housing I ings 1* and 2 so that housing -1' maybe lifted otl of its guide plate 6 2 Q "When the book isin the last described Open position an desired number of, sheets 5 may e removed therefrom while being retained in position on guide "plate 68. VVhen'it is desired to return these sheets'5 to the bookthe 'o-perationis very much facilitatedj due to the fact thatthey are in position on-guide plate 68' and the posts 69 carried by guide plate 68 may beeasilyinserted into the proper apertures'in' theishe'ets5. s I p The object of having guide plate 68 conthereby incrasingtheir'length between hous- I formed'toone side "of housing -1- is that y when the book is being closed one edge of housing 1" maybe placedover the edge of. guide plate 68 and as the book is closed hous ing'1- will move downwardly into registration'with guide plate 68'and1ii1to the position for permitting locking ofthe proper Itfwill be understood that either housing -1 or housing 2 maybe removed from its guide plate 68 depending upon which side of the book-it is desiredto open. v

It will also be understood'that slots. 7 3 are provided in sheets 5 for the'r'eception of flexible posts 27 'and 28 and :by the use of uide plates 68 it ispossible to have slots 3, of such'a shape that posts 27 and 28"may enter therein without any; i distortion of sheets 5.

The advantage of beingable to use slots 73 of such shape is that sheets 5 may be easily true of the ordinary apertures now provided for use with post binders, such last men:

tioned apertures beingof'a practically circular shape with a slit extending to -the edge of the sheet.

" It will also be understood that the num-i, 1 I

'ber of posts-69 carried by a guide plate 68 e 7 maybe varied as may the number of aper- 3 tures 72 or if desired apertures 72 may be eliminated. It will also be understood that the exact'sizejand shape of guide plates 68-- maybe varied to accommodate them to dif-f ferent sizes, types-andshapes of post binders without departing from the spirit of my invention, for altho I have shown and de- I scribed a specific structure and formof part as an exemplification of an embodiment of my invention I do not desire to restrict myself to the exact size, shape or arrangement" is V e and readily used in atypewriter which is not of parts as various changes may be made within the scope of the appended claims.

I claim:

1. In a loose leaf book, a pair of opposed convex back members, covers hinged to the back members and a concave plate in contact with the inner face of each back member and removable therefrom, and having a plurality of posts adapted to extend through openings in loose leaves.

2. In a loose leaf book, a pair of opposed convex back members, covers hinged to the back members and a concave plate in contact with the inner face of each back member and removable therefrom, and conforming substantially to the convexity of the back member, and having a'plurality of posts adapted to extend through openings in loose leaves.

3. In a loose leaf book, a pair of opposed back members having their opposite sides curved, covers hinged to the back members, and a plate having its, outer side curved in substantial conformity to the back member and adapted to engage the inner face of such back member and center the same, and hava ing a plurality of posts adapted to extend through openings in loose leaves.

4:. In a loose leaf book, a pair of opposed back members, covers hinged to the back members, and a plate having outwardly ex tending sides adapted to receive a back member therebetween, said plate having a plurality of posts adapted to extend through openings in loose leaves.

5. In a loose leaf book, a pair of opposed back members, covers hinged to the back members, and a plate having an outwardly extending side adapted to engage an edge of a back member and having a plurality of posts adapted to extend in apertures in loose leaves. 7

In witness whereof I have hereunto set my hand this 21st day of June, 1928.
